BEYOND WC25-4D-SD24.5-WC04
Industrial 4D Indexable U-Drill | 24.5mm Precision CNC Machining
High-Efficiency 24.5mm Indexable Drilling
The BEYOND WC25-4D-SD24.5-WC04 is a high-rigidity indexable insert drill engineered for rapid metal removal. Featuring a 24.5mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the definitive choice for high-speed internal cooling drilling. It is optimized for heavy-duty CNC machining in carbon steel, alloy steel, and stainless steel.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 24.5 mm | 0.9645" |
| Shank Diameter | 25.0 mm | 0.984" |
| Max Drilling Depth (4D) | 98.0 mm | 3.858" |
Recommended Cutting Parameters
Optimize your CNC holemaking with these settings for WC series rapid drills:
- Cutting Speed (Vc): 120 - 200 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Coolant: High-pressure internal cooling is mandatory for effective chip evacuation.
Premium Material & Optimized Spiral Flute
Constructed from high-performance alloy steel with specialized anti-vibration quenching, this WC04 insert holder ensures maximum rigidity. The wide spiral flute geometry is specifically engineered for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in 24.5mm deep hole drilling. The nickel-plated body minimizes friction and prevents chip welding during high-speed operations.
WC Series U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Stable performance on uneven or curved entry surfaces.
- Fast chip breaking on low-carbon and alloy steels.
- Requires higher spindle torque.
- Surface finish may require secondary finishing for high-precision bores.
Verified Customer Reviews

Questions & Answers
Q: Does this include the inserts?
A: No, this is the drill body only. You will need WC04 inserts.
Q: Can I use this on a manual drill press?
A: No, U-drills require high torque and precision coolant pressure found on CNC machines.
Q: What is the maximum drilling depth?
A: This 4D model can drill up to 98mm deep.
Pro-Tip: Choosing Drill Depth (2D to 5D)
- 2D/3D: Maximum rigidity; best for shallow holes and high-feed roughing.
- 4D (Current Model): The balanced universal standard for industrial deep-hole machining.
- 5D: Specialized deep-hole drill bit. Requires extreme coolant pressure.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
